To al?, whom/ z'ft may concern:

Be it known that I, ALPHONSE ZAoi-IAEY BoDEEAUx, a citizen of the UnitedStates, and a resident of Berwick, in the parish oi' St. Mary and Stateof Louisiana, have invented a new and Improved Shingle-Machine, of whichthe following is a full, clear, and exact description.

This invention relates particularly to attachments to shingle-sawingmachines in which the saw rotates in a horizontal plane, the objectbeing to provide a simple device for ejecting the spalts from themachine instead oi' manually removing the same, as is the usualpractice, thus obviating the possibility of cutting the attendants handsor lingers by the saw.

I will now describe a shingle-machine embodying my invention and thenpoint out the novel 'features in the appended claims.

Reference is to be had to the accompanying; drawings, forming a part ofthis specification, in which similar characters oi' reference indicatecorresponding parts in all the figures.

Figurel is a plan of a shingle-machine embodying my invention. Fig. 2 isa longitudinal section thereof. Fig. 3 is a sectional View showing aslight modiiication. Fig. 4 is a perspective View of the Spalt-ejector,and Fig. 5 shows a setting device therefor.

It may loe here stated that in Figs. l and 2 I illustrate what is termeda double-block machine, and in Fig. 3 is shown a singleblock machine.

Referring iirst to my invention shown in Figs. 1 and 2, 1 designates thebed-plate or table of the machine, and 2 a carriage movable lengthwisethereof through the medium of links 3 and a crank 4. These parts are ofthe usual construction, as are also the tilt-tables 5. arranged atopposite ends of the machine.v Mounted to swing on cross-bars 6 at theends of the machine are ejectors consisting of spring-actuated plates 7,which extend inward, the upper members of the springs 7 being arrangedto engage against the under sides oi' theI plates 7. From each plate 7 alatch-hook 8 extends downward and is designed to engage with alocking-bar 9, pivotedv at one end to a side rail of the bed-plate, asat 9b, and having its opposite end extended through an opening in theopposite side of thebedplate or table, and the bar is held yieldingly inits locking position by means of a spring 1.0. The lower end of the hook8, it will be noted, is inclined so that when the spring is presseddownward the incline will force the locking-bar 9 outward until the hookpasses the same. Then the spring 1() will draw the bar into engagementwith the hook. The plate is pressed downward to its locked position bymeans oi' a presser 11, which projects downward from an end bar of thecarriage. This presser is in the form of a bolt carrying a roller Il forengaging directly with the plate.

In the example shown in Fig. 3 the construction is practically the same,excepting that it is a single-block machine.

ln operation when blocks are placed in the carriage and the carriagereciprocated the devices ll will press the ejecting-plates downward totheir locked position, where they will remain during the sawing oi' theblock into shingles. When the block is reduced to a spalt and as thespaltis over a plate 7, the attendant by moving' the bar 9 releases thespring, so that it throws the Spalt outward, as indicated by dottedlines in Fig. 3. Two spalter push-blocks 9 are provided on the cross-barcarrying the plate 7 and serve to prevent a spalt from getting' underthe original push-blocks on the carriage. .In the single-block machinetwo narrow blocks may be placed side by side. 'The outer block, or theblock nearest the end of the carriage, may be oi less height than theinner block, and therefore it is more quickly reduced to a spalt, andwhen this point is reached and the spalt is over the spring it isejected, as above mentioned.

It will be seen that by my invention an attendant that may be onlyslightly familiar with the shingle-sawing device having thehorizontally-acting saw 13 may readily operate the machine withoutdanger of cutting' his hands or ingers. In other words, it does notrequire a skilled sawyer to operate the machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. In a shingle-machine having a horizontally-rotatingsaw and a reciprocating carriage, a spalt-ejecting spring-actuated plateattached to a fixed portion oi' the machine, a locking device for thespring-actuated plate, and a device on the carriage for moving the plateto locking position.

2. In a shingle-machine having a horizontally-rotating' saw, areciprocating carriage, a
